Thanks for the info. Could I get round the single value limitation with something like:
IN ((SELECT 'abc','def' FROM myTable)) Also, in the LIKE example, looks like I don't need single quote delimiters around the pattern? > > Message: 4 > Date: Thu, 3 Sep 2015 12:54:46 -0400 > From: Richard Hipp <drh at sqlite.org> > To: General Discussion of SQLite Database > <sqlite-users at mailinglists.sqlite.org> > Subject: Re: [sqlite] Variables in statements > Message-ID: > <CALwJ= > Mwy6Z07bWxUNACk6uAv2d6NmM8s4ETGcNbULw3jXZHH3g at mail.gmail.com> > Content-Type: text/plain; charset=UTF-8 > > On 9/3/15, Peter Haworth <pete at lcsql.com> wrote: > > > > SELECT * FROM myTable WHERE myKey IN (:1) > > > > If the value I supply to be used as :1 is a single integer, the SELECT > > finds the correct rows.

This latter seems like a livecode problem. Similar things > work in SQLite. See > https://www.sqlite.org/src/artifact/0f0ee61?ln=295 for example.
